Why Pay-As-You-Go?

You don't need to commit to a $30/month plan just to try out a few features. Add $5 and see if it works for you.

Casual users don't subsidize power users. Heavy users get the enterprise-grade volume they need without hitting artificial caps.

We enable auto-limits so you never accidentally spend more than you intended. You're in control.

Accessing shared community curriculums and practicing existing tests is 100% free. You only pay for AI generation.
